We could use assistance from people who have expertise in the following areas:

Database abstraction/layer integration

HTDB uses a home-brewed database abstraction layer built to MySQL and mSQL native
APIs. Ideally, this layer needs to be replaced with a more extensible database
layer with support for more databases. If you have experience in database abstraction
layers (in C), we'd love to hear from you!

Update: libdbi looks to be a nice piece of work, and libhtdb may move
to using that as the database abstraction layer.

Compiler writers and/or Flex/Bison gurus

The HTDB scripting language is written in C and a bit of a beast to maintain - it needs
to be replaced with a proper parser. Part of this project will be upgrading the current
language syntax to a completely tag-based (ala XML) format.

Does this sound masochistically interesting?
